These data are raw pass data and ancillary data.

---------------------------------------------------------------------------
source_information.csv
---------------------------------------------------------------------------
Information on the controlled release for each pass.

Pass ID: pass ID to correspond to pass detection results.
Filename: filename of the raw pass file.
Survey date: date of survey.
Source X utm: X utm location of the source (UTM Zone 12 N).
Source Y utm: Y utm location of the source (UTM Zone 12 N).
Source Z (m): elevation of the source above the ground.
U (m/s): pass averaged ground wind speed at release elevation.
Q (g/s): methane release rate.
Min azimuth (degrees): the minimum azimuth that is considered a true plume.
Max azimuth (degrees): the maximum azimuth that is considered a true plume.
Stability class: the Pasquill-Gifford stability class.

pass_data.csv
---------------------------------------------------------------------------
Raw pass data.

concs: concentration data in ppmv raw from drone.
x: x UTM position (UTM Zone 12 N).
y: y UTM position (UTM Zone 12 N).
z: elevation of the drone above ground level (m).
t: time in seconds from the start of the pass (s).
wspd: wind speed measured from the drone autopilot at flight elevation (m/s).
wdir: wind direction measured from the drone autopilot at flight elevation (degrees).
anomaly: derived anomaly (ppmv) (ignore this column as it depends on processing parameters).
plumes: sample boolean column to denote the existence of a plume (1 = True, 0 = False) (ignore this column as it depends on processing parameters).
theta: azimuth from the drone to the source (degrees).
dist: dist from the drone to the source planimetrically (m).
radial_conc: sample Gaussian concentration enhancement (g/m^3).
pass: the pass (referenced to the source_information.csv file).
